Everyone has different needs based on their specific malocclusions (bad bites) so it's best to talk with an Orthodontist in your area to learn what your timeline would be.  Some people  can get great results in as little as 12mo with full braces and others may need up to 3-4years.  An average length can be around 24mo.  She's right too, the cleaning and maintenance of your teeth will be made much easier when the teeth are properly aligned and your bite is fitting together.
